$24,000 A YEAR ON $5.2M OF WORK. THEN THE PRICING GOT FIXED.
Not $24,000 a month. $24,000 a year, on five million dollars of revenue, from a business the owner had run full time for years.
A $5.2M erosion control and SWPPP subcontractor was earning $24,000 a year in net profit, a 0.5 percent net margin, because he knew his revenue per site and not his cost per site visit. Recurring inspection and BMP work feels stable, so it gets priced like a commodity while the true cost of mobilization frequency, labor burden, fuel, vehicle wear, insurance, and compliance documentation goes untracked at the job level. Rebuilding job costing per site showed that a meaningful share of his active sites were priced below break even, by a few percentage points each, which at his volume was the whole difference between making money and making nothing. The work was repriced, some GCs accepted the new rates and some didn't, and the ones that didn't represented $1.6M of revenue that was break even or negative. When that work rolled off, revenue dropped and net profit went up by $1,081,000. The year finished at $1,105,000 in net profit, a 30 percent net margin on $1.6M less revenue than the year before.
He had been performing $1.6M of work every year that cost him money to perform. It showed on the P&L as business activity and it was a subsidy to GCs who had found the cheapest erosion control sub in the market.

$24,000 A YEAR ON FIVE MILLION DOLLARS OF WORK.
A $5.2M erosion control subcontractor was making $24,000 a year in net profit. Not $24,000 a month. $24,000 a year, on five million dollars in revenue. That's a 0.5% net margin on a business the owner had been running full time for years.
He wasn't doing anything wrong in the field. His crews were executing, his GCs kept calling him back, and his bids were competitive. From the outside, the business looked like it was working. From the inside, the owner was effectively paying himself less than minimum wage for the privilege of running a multi-million dollar operation.
Twelve months later, the same business produced $1,105,000 in net profit. Same owner, same crews, same trades, and $1.6M less revenue. Here's what was broken.
SWPPP WORK HAS A HIDDEN COST PROBLEM.
Erosion control and SWPPP subcontracting has a specific financial profile that most owners in this trade don't fully account for. The work is often recurring: weekly or biweekly site visits, BMP installation and maintenance, and inspection reports. That recurring structure feels stable, but it creates a costing problem that's easy to miss.
Because the visits are routine, owners tend to price them as commodity services. Low margin, high volume, keep the crews moving. What they don't account for is the true cost of mobilization frequency. Every site visit has a real cost: labor burden, fuel, vehicle wear, insurance allocation, and time spent on compliance documentation. When those costs aren't tracked at the job level and compared against what's being billed, the margin erodes invisibly.
This owner had dozens of active sites at any given time. He knew the revenue. He didn't know the cost per site visit, and he didn't know which sites were producing margin and which ones were eating it. He was running five million dollars of work through a financial system that couldn't answer the most basic question, which is which jobs are making money.
THE REVENUE DROP THAT MADE HIM MORE PROFITABLE.
When we rebuilt the job costing structure, the numbers told a clear story. A significant portion of his active sites were priced below break even. Not by a lot, a few percentage points, but at his volume a few percentage points was the difference between making money and making nothing.
We repriced the work. Some GCs accepted the new rates and some didn't. The ones that didn't represented $1.6M in revenue that was either break even or negative margin, and when that work rolled off, revenue dropped. Net profit went up by $1,081,000.
He was doing $1.6M worth of work every year that was costing him money to perform. That revenue appeared on his P&L and looked like business activity. In reality it was subsidizing GCs who had found the cheapest erosion control sub in the market and were getting work done at below cost rates. Letting that revenue go wasn't a loss, it was the most profitable decision the business had made in years.
Losing $1.6M of revenue was the most profitable decision the business had made in years.
THE COST OF COMPLIANCE DOCUMENTATION.
There's a line item in erosion control subcontracting that almost never gets allocated correctly, which is the labor cost of compliance documentation. Inspection reports, BMP installation records, and corrective action logs all take hours somebody has to work.
On a site with active SWPPP requirements, a qualified inspector might spend two to four hours a week on documentation alone. That time has a real cost, and it almost never gets built into per site pricing because it feels like overhead rather than job cost.
It's not overhead. It's a direct cost of performing that specific site's work. When it gets lumped into overhead it inflates your overhead rate and makes all your work look less profitable than it is. When it gets tracked at the job level you can see which sites are worth the documentation burden and which ones aren't.
$1,105,000 IN NET PROFIT, ON LESS WORK.
The final number for the year was $1,105,000 in net profit, a 30% net margin on $1.6M less revenue than the prior year.
The owner's day didn't change much. His crews were still doing erosion control and he was still managing GC relationships, site inspections, and compliance requirements. The difference was that every dollar of work the business took on was work the business profited from.
He described it as the first year he felt like he was running a real business instead of just staying busy. That's what a real cost system does. It turns activity into profit.
